(54) Light scanning unit and electrophotographic image forming apparatus using the same


(57) A light scanning unit and an electrophotographic image forming apparatus employing the same. The light scanning unit includes an imaging optical system including, when a path of one of the light beams directed to one of the surfaces disposed relatively far from the deflector is referred to as a first light path and when a path of one of the light beams directed to one of the surfaces disposed relatively close to the deflector is referred to as a second light path, light paths in which both of a section of the second light path before a first change of the second light path and a section of the second light path after the first change of the second light path intersect a section of the first light path after a second change of the first light path.
